Description

Technical Field

[0001] This invention relates to the field of coal mine roadway support equipment technology, and specifically to an intelligent remote-controlled airborne temporary support device. Background Technology

[0002] Safety issues related to support during tunneling operations have long been a technical problem plaguing coal production. The inability to provide timely and effective support after tunnel excavation frequently leads to injuries. To facilitate appropriate adjustments to the support structure based on actual support conditions, Chinese Patent CN113494307A discloses an onboard temporary support device, comprising a mounting base, a moving platform, and a support plate. The mounting base has a second threaded shaft movably mounted inside, with two second internal threaded sleeves threaded onto the shaft. A connecting plate is fixedly mounted on the top of each of the two internal threaded sleeves. The top of the mounting base has two slots. Connecting columns are fixedly mounted at all four ends of the top of the connecting plate, forming a pair of columns. Each pair of columns extends through one of the slots to the top of the mounting base. The moving platform is mounted on the top of the mounting base via the four connecting columns. Two hinge seats are provided on one side of the top of the moving platform, with a connecting shaft movably mounted between the two hinge seats to facilitate adjustment of the position and angle of the support plate. However, the angle and position adjustment of the support plate require two drive motors, which still makes the support adjustment inconvenient. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of existing technologies and propose a smart remote-controlled airborne temporary support device with a simple structure, which can realize the angle and position adjustment of the support plate through only a single drive device.

[0004] The technical solution adopted by this invention to solve its technical problem is:

[0005] A smart remote-controlled airborne temporary support device includes a support plate, a support device for supporting the support plate, a tilting device for driving the support plate, and a control system. Both the support device and the tilting device are mounted on a base plate. The tilting device includes a support plate fixing seat, a front and rear drive device, a support rod, a connecting seat, and a connecting rod. The front and rear drive device is controlled by the control system. The support rod is vertically mounted on the base plate, and the front and rear drive device is horizontally mounted on the support rod. A connecting seat is fixedly mounted at the output end of the front and rear drive device, and a vertical slide rail is provided on the connecting seat. One end of the connecting rod is fixedly connected to the support plate, and the other end is slidably connected to the vertical slide rail and can rotate vertically relative to the vertical slide rail. The support plate fixing seat is mounted on the base plate, and a horizontal slide rail is provided on the support plate fixing seat. The end of the support plate is slidably connected to the horizontal slide rail and can rotate vertically relative to the horizontal slide rail. When the support plate needs to be deployed, the front and rear drive devices are activated. These devices move the connecting seat to the right. Since the connecting rod is fixedly connected to the support plate, it drives the support plate to rotate. During the rotation of the support plate, the other end of the connecting rod moves up and down in the vertical slide. When the support plate rotates to a horizontal position, the support device provides support for the support plate. At this point, the connecting seat is driven to the right again, causing the end of the support plate to slide to the right in the horizontal slide. This same flipping device not only enables the horizontal placement of the support plate but also allows for adjustment of its front and rear positions to meet different operational needs, offering flexibility and convenience.

[0006] Furthermore, the front and rear drive devices are hydraulic cylinders, pneumatic cylinders, or electric telescopic rods.

[0007] Furthermore, the front and rear drive devices are embedded in the support rod, which helps to save space.

[0008] Furthermore, the top height of the vertical slide is not less than the height of the top of the connecting rod when it is rotated to its highest point, which enables the support plate to rotate to a vertical state.

[0009] Furthermore, a roller is fixedly connected to the end of the support plate. The roller surface is provided with an annular protrusion. The upper and lower surfaces of the horizontal slide are provided with grooves that cooperate with the protrusion. The annular protrusion is inserted into the groove, which can both enable the roller to slide left and right in the horizontal slide and prevent the roller 11 from falling off the horizontal slide.

[0010] Furthermore, the end of the horizontal slide near the support rod is arc-shaped to match the shape of the roller, which facilitates the flipping action when the roller moves to the end.

[0011] Furthermore, the connecting rod is arranged perpendicular to the support plate, which facilitates the connecting rod driving the support plate to rotate.

[0012] Technical effects of the present invention:

[0013] Compared with the prior art, the intelligent remote control airborne temporary support device of the present invention can realize the flipping of the support plate and the position adjustment of the support plate in the horizontal state through the setting of the flipping device. It is simple to operate and can better meet the operational needs; the intelligent remote control of the support is realized through the control system. Attached Figure Description

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0023] Example 1:

[0024] like Figure 1-4As shown, this embodiment relates to an intelligent remote-controlled airborne temporary support device, which includes a support plate 1, a support device for supporting the support plate 1, a flipping device for driving the support plate 1, and a control system; the support device and the flipping device are both mounted on a base plate 2; the support device is a support column 10; the flipping device includes a support plate fixing seat 3, a front and rear drive device 4, a support rod 5, a connecting seat 6, and a connecting rod 7; the front and rear drive device is controlled by the control system.

[0025] The front and rear drive devices 4 are hydraulic cylinders embedded in the support rod 5; the support rod 5 is vertically mounted on the base plate 2, and the front and rear drive devices 4 are horizontally mounted on the support rod 5. A connecting seat 6 is fixedly mounted on the output end of the front and rear drive devices 4. The connecting seat 6 includes a vertical connecting seat a61 and a horizontal connecting seat b62. The horizontal connecting seat b62 is fixedly connected to the output end of the front and rear drive devices 4. The vertical connecting seat a61 is fixedly mounted on the horizontal connecting seat b62, and a vertical slide rail 8 is formed on the side of the vertical connecting seat a61. One end of the connecting rod 7 is vertically fixed to the support plate 1, and the other end is slidably connected to the vertical slide rail 8 and can rotate vertically relative to the vertical slide rail 8. The top height of the vertical slide rail 8 is not less than the height of the top of the connecting rod 7 when it rotates to its highest point, enabling the support plate 1 to rotate to a vertical position. The support plate fixing seat 3 is set on the base plate 2, and a horizontal slide rail 9 is provided on the support plate fixing seat 3. The end of the support plate 1 is slidably connected to the horizontal slide rail 9 and can rotate vertically relative to the horizontal slide rail 9. When it is necessary to unfold the support plate 1, the front and rear drive device 4 is activated. The front and rear drive device 4 drives the connecting seat 6 to move to the right. Since the connecting rod 7 is fixedly connected to the support plate 1, the support plate 1 is driven to rotate. During the rotation of the support plate 1, the other end of the connecting rod 7 moves up and down in the vertical slide rail 8. When the support plate 1 is rotated to a horizontal position, the support device just supports the support plate 1. At this time, if the connecting seat 6 is driven to the right, the end of the support plate 1 can slide to the right in the horizontal slide rail 9.

[0026] A roller 11 is fixedly connected to the end of the support plate 1. The surface of the roller 11 is provided with an annular protrusion 12. The upper and lower surfaces of the horizontal slide rail 9 are provided with grooves (not shown in the figure) that mate with the protrusion 12. The end of the horizontal slide rail 9 near the support rod 5 is arc-shaped to match the shape of the roller 11. The annular protrusion 12 is embedded in the groove, which not only allows the roller 11 to slide left and right in the horizontal slide rail 9, but also prevents the roller 11 from falling out of the horizontal slide rail 9.

[0027] The control system includes a PLC, a wireless remote controller, and a vehicle-mounted wireless receiver. The wireless remote controller collects the status of switches and handles in real time and transmits the information to the vehicle-mounted wireless receiver via a wireless network. The vehicle-mounted wireless receiver communicates with the PLC via CAN / RS485 to control the operation of the front and rear drive units, thus achieving remote control of the tunneling machine support. The tunneling machine can be operated via the wireless remote controller to complete all tunneling support work. Operators can control the tunneling machine from within 100 meters of the tunneling site, achieving human-machine separation, ensuring safe production in the coal mine, and improving the operator's working environment.

[0028] Working principle: When the support plate 1 does not need to be deployed, such as... Figure 1 As shown, the support plate 1 is in a vertical position. When it is necessary to deploy the support plate 1, the front and rear drive device 4 is activated. The front and rear drive device 4 drives the connecting seat 6 to move to the right, as shown. Figure 2 As shown, since the connecting rod 7 is fixedly connected to the support plate 1, it drives the support plate 1 to rotate. During the rotation of the support plate 1, the other end of the connecting rod 7 moves up and down in the vertical slide rail 8. When the support plate 1 rotates to a horizontal state, the support device just supports the support plate 1. At this time, continuing to drive the connecting seat 6 to the right allows the end of the support plate 1 to slide to the right in the horizontal slide rail 9, as shown. Figure 3 As shown, the position of the support plate 1 can be adjusted left and right. The same flipping device can not only achieve horizontal placement of the support plate 1, but also adjust its front and rear position to meet different operational needs, offering flexibility and convenience. When it is necessary to reset the support plate 1, the connecting seat 6 is pulled to the left by the front and rear drive device 4. This first positions the roller 11 at the end of the support plate 1 at the leftmost end of the horizontal slide rail 9. Continuing to drive to the left, the support plate 1 is flipped upwards by 90 degrees and then reset.

[0029] Example 2:

[0030] like Figure 5 and 6 As shown, this embodiment relates to an intelligent remote-controlled airborne temporary support device, whose main structure is the same as that of Embodiment 1. The difference lies in that the support device is a telescopic rod 15, the bottom of which is slidably connected to the base plate 2, and the top is hinged to the bottom of the support plate 1. Specifically, a sliding plate 14 is provided at the bottom of the telescopic rod 15, and a track 13 for embedding the sliding plate 14 is provided on the base plate 2. When the support plate 1 is flipped upward, the telescopic rod 15 moves to the left along the track 13 while being stretched upward, moving with the flipping of the support plate 1.

[0031] The above-described specific embodiments are merely specific examples of the present invention. The patent protection scope of the present invention includes, but is not limited to, the above-described specific embodiments. Any appropriate changes or modifications made by a person skilled in the art that conform to the claims of the present invention should fall within the patent protection scope of the present invention.
